FASTEIIING DEVICE.

Specification of Letters Eetent.

, "i s r Application filed March 6. 1916. Serial No. 82,880.

ing the fastening device therefrom; to con real the spring element andrender the structure pleasing" to the eye; and to cheapen the expense oiconstruction; and to attain these QIHlS in a structure which is easy tonianipnlate.

To the above ends essentially my invention consists in such parts andcombinations of parts as fall within the scope of the ap pended claims.

in the accompanying drawings which form a part of this specification,Figure l is a siilc elevation of the complete button, Fig. '3, a similarelevation. showing the connecting members at a different angle, 33, alongitudinal section of the device. Fig. 4. a detail view of thesliclahle link member with the spring located tl1erein..i*ig'.-5, adetail view of the housing link memher. Fig. 6, a section on line (56 ofFig. 1. Fig. 7 is a detail showing the interlocking of the lips of thehousing.

Like reference characters indicate like parts throughout the views.

In the drawings 1 represents he button heads of any usual preferredconstruction comprising in the present instance outer shells 2 andlinings 3 engaged in the outer shells by downwardly bent flanges 4 andin tegral with which are central loops 5 adapted to engage the ends ofthe connecting member.

The central member comprises a housing link 6 shown in detail in Fig. 5comprising parallel shells l connected at one end by an tc at and at theother end by int iO-Cl ZKl. lips 9'. 9 which when overlapped as seen. inFig. 7 form a post 10. This complete honsing link has side openings iiand one of its posts such as 10 engages one of the loops 5. Inside thislink is a heiicai spring abet; ting at one end against the post 5% anti.other end prcsing; against one one. of ii l3 which a1. inclose: otherend pa.
